How many people, time and budget did you need to build your backend?

Question

Hey there! I'm interested in understanding what is the typical investment (in terms of people, salary, and time) to develop a backend solution (leaving maintenance aside). I'd also be nice if you can roughly explain the scale and complexity of the backend solution you built. For example, I worked on a knowledge-graph backend solution consisting of an API and N workers consuming tasks from a queue that took ~2 years to develop, 3-4 full-time backend engineers and a total investment of around 300k USD.

The data will be apples and oranges. It won't tell you anything.
A typical CRUD back-end can be built in a day or two by a single dev, especially if s/he is not worrying about writing DRY, elegant code that is easy to maintain.
A serious back-end solving novel problems, dealing with high demand, or incorporating many asynchronous processes could easily take 5 devs a full 6 months to build.
You have to be much, much more specific.
